'91 ECU Tweaking? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok, I have to eventually do something with the ECU, and I'd like to somehow reprogram it myself as opposed to spending $1,000 for an aftermarket unit or $300 for a piggyback. As for right now though, I just need the rev limiter and speed limiter killed.

Is there any way to do this with a laptop, cable, and downloadable software, or is there another ECU option I'm missing here? It seems there's got to be some low cost option available.

ka or sr? there are several shops that will tune either. secret services in florida tunes both, i know. there is also a KA rom tune on phase2motortrend. SR rom tunes are on ebay all the time...

It's the KA24DE, and I'll be in Spokane, WA. A bit far from Florida.

i think secret services might be offering off the shelf units.

Ghettokracker71 · 05-05-2004, 02:38 PM

Get a Badbiki daughterboard, I have tons of roms for the sr and KA. If you wanna be in the know check out zcontrol.net and its forum ztechz.net

ZControl looks to still be in beta or something, but I'll gladly keep monitoring it. Until then, does anyone know of a way to remove the speed limiter and rev limiter without fucking directly with the ECU? Cutting wires or re-routing them is cool, but I don't have the ability to fuck with the ECU itself as of yet.

im currently testing the sr/ka zcontrol for mike. There are still some bugs though. Rom editor is available from 925style and is for sr's and ka's. I wouldnt cut any wires though.
